Hi All,
there has been much discussion here and many other places about the
suggested working frequencies offered by WSJT-X. In general we have
followed the crowd and set default frequencies that have already become
common usage. This is because we do not claim to be the arbiters of band
plans, nevertheless we are accused of forcing users to go to certain
frequencies that may be at odds with local band plans or even licence
regulations despite this being the sole responsibility of the licensed
operator themselves.
The amount of heated discussion now means the we have to try and find a
better path. To this end I have enhanced the working frequencies table
in the WSJT-X settings to include the IARU region as well as the mode
and the actual frequency. Like the mode the IARU region may be set to
"All" (previously blank) which means the frequency is common to all
three IARU regions. I have not yet committed the changes as I would like
some consensus on frequencies for all the modes WSJT-X offers on all the
bands where those modes are useful and for each IARU region where the
region defines a band plan that requires operation away from currently
accepted global frequencies. Once we have a reasonably complete set we
can run them past the IARU region coordinators and band planners for
approval. Note that there can be more than one frequency per
Region/Mode/Band triple but note that where WSJT-X has to make an
automatic decision it will pick the lowest frequency for the band e.g.
in automatic coordinated WSPR band hopping.
The intention is to change the settings key used to save the working
frequency suggestions for the next release, this will automatically
reset all user's frequency tables to the new default values. As now
users may adjust, add or remove working frequency table entries to their
own preference. I have also added the ability to save the frequencies
table to a file, replace the table by load from a file and merge a file
into the table.
The frequencies offered in the main window band drop down list will be
those that match the current mode and the IARU region specified in the
"Settings->General" panel.
It should be noted that band planners may feel that having HF style
JT9/JT65/WSPR operation where all users use the same dial frequency is
not sensible, they may not realize the benefits that a multi-signal
decoder combined with Internet spotting services like pskreporter.net,
hamspots.net, wsprnet.org, etc. bring. In fact sometimes there are
hidden agendas that mean it would be better if operators spread out
across the suitable available spectrum. We must try and address these
subtleties as well as trying to find suitable global frequencies where
we can make inter-IARU region DX QSOs when the propagation permits.
So I am looking for Region/Mode/Frequency triples where Region may be
"All" for a global frequency, mode may be "All" where there is no mode
specific allocation for a band (this may apply to microwave bands for
example where the frequency chosen for a sked could be one of many and
the mode largely up to the operators preference, in this case the
working frequency is really only a convenient CAT band switch and the
real working frequency would be set using the rig VFO or by direct entry
into the WSJT-X band selector).
The current default list with a trivial addition of IARU Region="All" to
each entry is (frequencies in Hertz):
